Gelenkstücke GN 638 sind universell einsetzbar. Die Ausführungen mit Kunststoffdruckstück verhindern Beschädigungen an empfindlichen Oberflächen. Bei Anwendungen in aggressiveren Umgebungen oder mit höheren Belastungen sind die Edelstahlvarianten zu bevorzugen.
Der Kugeldurchmesser d3 ist kleiner als der Kerndurchmesser des Gewindes, sodass sich die Verstellspindel kugelseitig einschrauben lässt. Das Kugelende des Gewindestiftes lässt sich einfach in das Druckstück eindrücken und bei Bedarf wieder demontieren.
Die Angaben über die statische Belastbarkeit der Kunststoff-Druckstücke sind Richtwerte, die durch eine Versuchsreihe ermittelt wurden. Dabei wurde das Druckstück über den Gewindestift senkrecht belastet. Bei der angegebenen Belastung von 3,5 kN wurde weder eine bleibende Deformation des Druckstücks festgestellt, noch kam es zum Bruch.
